How Does the Heating and Temperature Control Work?
The Connect uses conduction heating. The temperature range extends up to 220 °C, and the heat-up time is around 5 seconds.
Conduction heating heats the material directly via the chamber wall. This ensures rapid heating and even extraction when the chamber is well filled.
Research context: A study in the Journal of Pharmaceutical Sciences (Hazekamp et al., 2006) showed that vaporization at controlled temperatures releases over 95 % of the desired active compounds, while combustion by-products are largely avoided. Source: PubMed 16637053
How Do I Charge the Battery Properly?

Verdict
The Connect is a portable vaporizer by G Pen with conduction heating. It is aimed primarily at beginners and users looking for a simple device. Our price comparison shows it from 55.08 € at 17 shops.
Use with a Bong
Place the Connect on a bong with a 14mm or 18mm ground joint. Load the concentrate into the quartz chamber and select the temperature. Three levels available: low for flavour, high for clouds. The water filtration cools the vapour significantly.
Chamber Types
Three chamber options: quartz for flavour, ceramic for even heat and titanium for rapid heating. The chambers can be changed without tools — simply pull out and insert.
Connect as a Hybrid Solution
The DaVinci Connect combines a portable vaporizer and water pipe adapter in one device. Simply remove the mouthpiece and place the Connect directly onto a 10mm glass joint — the water session is ready. The ceramic chamber holds 0.25 g and extracts the material evenly thanks to hybrid heating. Three Smart Paths automatically guide you through rising temperature levels.
Connect Temperature Control
The Connect offers stepless temperature control from 175 to 221 degrees Celsius. The three pre-programmed Smart Paths cover different preferences: Path 1 (175-190°C) for mild flavour, Path 2 (185-200°C) for balanced sessions, Path 3 (195-221°C) for maximum vapour density. The app allows individual paths with custom temperature levels and time intervals.
Connect Cleaning
Sweep out the ceramic chamber after every third session with the included brush. Soak the mouthpiece and the glass adapter weekly in isopropanol and rinse with warm water. The air path can be disassembled for thorough cleaning. The 10mm adapter deserves particular attention: condensate builds up here quickly. A pipe cleaner with isopropanol removes residue in seconds.
Connect Battery and Charging
The fixed battery lasts 5-6 sessions per charge. USB-C charging takes around 90 minutes. The OLED display shows the charge level as a percentage. Passthrough charging is not available — do not use the Connect while charging. For longer evenings, a short top-up charge is recommended: 20 minutes on the cable is enough for 2 more sessions.
